Electroylsis- The Basics

  • When you want to break an ionic compound with electric current, this is called Electrolysis.
  • It has to be molten or a solution.
  • Electrons are taken from ions at a positive electrode (anode) and a negative electrode (cathode).

Example- Lead Bromide


As Lead is positive it goes to the negative electrode (Cathode) and Bromine is negative to it goes to the positive electrode (Cathode). There are half-equations that go with this:

Pb2+ + 2e- = Pb

2Br = Br2 + 2e-

Aqueous Solutions

There are another two elements if you cannot
